PISTON-ROD PACKING.

SPECIFICATION forming part Of Letters Patent NO. 636,101, dated October 31, 1899.

Application filed February 9, 1899. Serial No. 705,102. (No model.)

To all whom it may concern.-

Be it known that I, JOHN BADEKER, a citizen of the United States, residing at Omaha, in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements in Piston-Rod Packing; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to piston-rod packing.

The object of the invention is to provide a self-adjusting metallic packing adapted to conform closely to and form a tight joint with the piston rods of engines, pumps, valvestems, &c.

The invention consists in the combination of a stuffing-box,apiston-rod working through said box, a spherical or ball joint between the bottom of said box and the piston-rod, a packing-holder consisting of a ring having seats or sockets for the metallic packing, the walls of the partitions between which are parallel with each other, Babbitt or other suitable metal segments seated in the sockets, having beveled faces, and a follower having hollow conical faces bearing against the packing-segments and having notches or recesses to register with the partitions between the segments.

In the drawings forming a part of this specification, Figure l is a section showing my improved packing as applied to the pistonrod of an engine or pump. Fig. 2 is a perspective of the packing-holder. Fig. 3 is a bottom perspective of the hollow conical follower. Fig. 4 is a perspective of one of the metallic packing-segments.

1 is a cylinder-head having the usual perforation or hole for the piston-rod and having a concave or spherical socket 2 formed therein, and having the usual stuffing-box 3. Embracing the piston-rod and fitting in the concave socket is a ball-joint ring 4, and embracing the piston-rod and bearing upon the balljoint ring is a packing-holder consisting of a ring 5, provided with a plurality of seats or sockets, the walls of the partitions 6 forming the sockets being parallel with each other. Seated in the sockets of the holder are a series of radially-movable packing-segments 7 7, of Babbitt or othersuitable metal, the outer faces of these segments being beveled, as shown in the drawings. Bearing upon these radially-movable segments is a hollow conical follower 8, the follower being provided. with notches 9, which register with the partitions 6 of the segment-holder. The conical follower is caused to bear with pressure against the packing-segments and cause them to impinge and fit closely against the piston-rod by means of the spring 10, abutting against a ring or the usual glands ll of the stuffingbox. The notches or recesses in the follower should be somewhat deeper than the height of the partitions or bosses on the holdingring, so that the follower may always bear upon the packing-segments notwithstanding wear on the same. partitions between the seats or sockets for the packingsegments should come within about one thirty-second of an inch of the piston-rod only, so as to allowthe segments or packing-sections to come together all around the rod. The ball-bearing between the piston-rod and the cylinder-head relieves the piston from strain in case the same should not be exactly in line. I

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is'

1. In piston-rod packing, the combination of a stuffing-box having a concave or spher ical seat, a ball-joint ring adapted to fit the seat, a packing-holding ring having a plurality of seats, as described, a plurality of me tallic packing-segments fitting in the holder, a conical follower bearing against the packin g-seg ments and a spring for holding the fol lower in contact with the segments, substantially as described.

2. In piston-rod packing, the combination of a stuffing-box, a packing-holder ring having The edge or angle of the radial seats separated by partitions or bosses, in contact with the segments, substantially as so that the seats are provided with parallel described. 10 walls, a plurality of packing-segments fitting In testimony whereof I aifix my signature in the ring or holder, a conical follower bearin presence of two Witnesses.
